Consequently, when the lever has been moved to its said position, the said exposed portion of the fastening means will serve as a stop for limiting the motion of thelever in the said direction, it being evident that the clamping of the portion 8 of the spring member to the removable section of the pen will prevent a longitudinal movement of the said spring member (and hence of the said fastening means 18) withrespect to the barrel of the pen.

To insure a proper alinement of the lever 3 with they spring shank 6 engaged thereby and with the said fastening and limiting means 18, I provide means associated with the spring member andthe barrel for preventing relativey rotation thereof. 'ljhe means used for this purpose may be varied asdesired, two different forms being shown in Figs. -5- and -6-. In Fig. -5-, the barrel 1 is equipped at its forward end with an inner reinforcing tube 19 secured nonrotatably to the barrel by suitable indentations 2O and equipped with an inwardly projecting ledge formation 21, which ledge formation is adapted to register both with a longitudinal groove in the outer surface of the plug portion 15 of the pen-carrier and with a corresponding peripheral notch 22 in the annular portion of the spring member. It will be evident from Figs. `4r and -5, that when the members are assembled, the said ledge or ridge 21 will coperate with the said groove and notch to prevent a rotary movement of both the pen-carrier and the spring or pressure-bar carrier with respect to the barrel of the pen. Consequently, the lever 3 will at all times be main-y tained in radial alinement with the spring shank 6 engaged thereby and with the stop formation of the fastening means.

However, I do not wish to be limited to this or other details of the construction heretofore disclosed, as the same might be modied in many ways without departing from the spirit of my invention. For example, instead of equipping the annular portion 8 of the spring member with a peripheral notch, the portion of the said annular member diametrically opposite the shank may be bent forwardly of the pen to form a lip engaging a recess upon the rear end of the plug portion 15 of the pen-carrier, thereby preventing the said spring from rotating with respect to the pen-carrier, while the latter in turn be locked against rotation by means of a groove engaging a corresponding formation in the bore of the barrel.

It will be evident from the drawings, that both the ink-sack and the spring member (together with the pressure-bar carried by the latter) may be secured to the pencarrier or removable section of the pen before the the pen-carrier by removing the locking member 16, thereby permitting this portion to placed.

I claim as my invention:

y1. A fountain vpen including a barrelA equipped on vone side with a slot, a pen-carrier carried thereby, housed by the barrel and connected to the pen-carrier;l and sackecompressing means,

including a lresilient bar interposed between the barrel and the ink-sack and. extendin longitudinally of the latter opposite the slot therein, the latter adapted to 'receive baractuating means, said-barY equipped with Ia portionextending transversely of the barrelV and abutting against a portion of .the pencarrier, an ,auxiliary Vmember carried :by fthe pen-carrier and clamping the said transverse portion of the resilient bar thereon, there being cooperating formations upon the barrel and the said transversel portion ofthe resilient bar for preventing relative rotation thereof about the axis o tiereby maintaining said bar opposite said s ot.

2. A fountain pen includinga barrel, a pen-carrier carried thereby; a compressible ink-sack housed by the barrel and connected to the pen-carrier; a` pressure-bar interposed between the ,said sack and barrel; a spring member secured to the said pressure bar and extending longitudinally of the barrel and equipped at its forward end with a portion extending transversely of the barrel, and abutting against a portion of the said pencarrier; and an auxiliary membercarried by Athe pen-carrier and engaging the said transverse portionof the spring member to clamp.

the latter between the saidauxiliary member and the said abuttingportion ofthe pencarrier.

3. A fountain pen including a barrel, a compressible ink-sack housed thereby, a pressurebar interposed between the said sack and barrel, a spring member secured to the said pressure-bar and equipped at one end with an annular portion'extending transversely of the barrel, a pen-carrier mounted in the barrel and liavinga portion extending through the said annular portion of the spring member, and an auxiliary member mounted upon the pen-carrier and engaging the said transverse portion of the spring member to clamp the latter betweenv the said auxiliary member and the pen-carrier.

4. A fountain pen including a barrel, a

be readily re` a compressible ink-sack the barrel and orate after prolonged service, the latter may Y readily be detached from gse pen-carrier carried thereby, a compressible gaging the said perforated portion of the ink-sack housed by the barrel and connected spring to clamp the latter between said lockto the said pen-carrier, a pressure-bar intering member and a portion of the pen-carrier. posed between the ink-sack and the barrel; In testimony whereof I have signed my a spring secured to the said pressure-bar, the name in presence of two subscribing witsaid1 springf having ail enddportion equiplped nesses.
